Knicks general manager Scott Perry said there still is no timetable for Kristaps Porzingis’ return from a torn left ACL. Perry said the Knicks would know better late summer August when Porzingis might come back. “I don’t think there’s a determination to be made,” Perry said. “Six, seven months out, you have a better chance to have a better time window. “You talk to most medical doctors, you really can’t pinpoint how many months it’s going to be. [You have] a better estimate six, seven months out after surgery is completed. So who knows when that will be?”
